SGG 421 

SGG 421Item Number: 744.421.1

In combination the SGG 421 and the EFM 113B build a static supervision unit.

The device monitors the sensor's current consumption and alerts (potential-free relay contact) in case the value is too high due to a contamination of the modulator system. Breaks are also detected and alarm is raised.

At the SGG 421 a upper (positive) and lower (negative) limit can be set.The limits can be set over controls or with the optional software.

In case of over- oder under-running of the limits, the corresponding relay switches. Therewith counteractive measures as e.g. air ionizers can be activated or an alarm can be raised.

The devices are mounted on a top hat rail.
